Embodiment

[0058] According to the G.984 protocol marked by GPON, each ME has a 16-bit Entity Class and a 16-bit Entity ID, and these two data uniquely identify an ME.

[0059] Therefore, in this embodiment, Entity Class and Entity ID are combined as a 32-bit index, and all MEs are stored in the AVL tree in an ascending manner, that is, in this embodiment, the 32-bit index formed by merging Entity Class and Entity ID is used as Unique identification of each ME data.

[0060] And the AVL tree that the present embodiment adopts is a kind of self-balancing binary search tree, simply speaking, AVL tree is a binary tree, and each node is about any node in its left subtree and is smaller than its The right subtree, and the height difference between the left subtree and the right subtree of each node is not greater than 1. The feature of small height difference ensures that the height of the tree is low, so the search efficiency is high.

[0061] Moreover, the AVL tree storing ME data needs t...

Abstract

The invention discloses an operation method for a light node management entity and, a GPON system. The operation method comprises steps that: S11, each management entity in one light node is stored in a memory in an AVL tree mode according to identification data of the management entities; S12, configuration data including a newly-established management entity is sent to the light node by a light line terminal through an OMCI; and S13, the newly-established management entity is stored in the memory based on the configuration data, and the newly-established management entity is inserted in an AVL tree formed by all the management entities in the memory according to the identification data of the newly-established management entity. According to the operation method for the light node management entity, and the GPON system, ME data is stored by utilizing the AVL tree, and thereby storage efficiency and a searching rate are improved.

Description

technical field [0001] The invention relates to an operation method of an optical node management entity and a GPON system, in particular to a method for adding, reading, modifying and deleting an optical node management entity utilizing an AVL tree and a GPON system. Background technique [0002] With the continuous evolution of information technology and the continuous improvement of user requirements, more and more optical access technologies have been put into practical use. [0003] GPON (Gigabit-Capable PON) is one of the mainstream optical access standards. Compared with EPON (Ethernet Passive Optical Network), it has more flexible and fine-grained control capabilities for terminals. , Inevitably, GPON's control protocol OMCI (ONTMagement and Control Interface optical node management and control interface) is also larger and more complex than EPON's control protocol OAM (Operation Administration and Maintenance). [0004] OMCI's management of optical nodes is accompl...
